thinkphp5 使用phpoffice/phpspreadsheet导入和导出excel
PHPExcel已经被废弃在PHP7.2中已经无法获取更新，官方重新开了一个新包phpspreadsheet
composer安装：
composer require phpoffice/phpspreadsheet一，导出，
1，view中：
导出
,2，在控制器中写方法
public function outExcel(){
$param = input();
$where = [];
$where['a.order_status'] = ['between',[1,7]];
if (isset($param['order_num']) && !empty($param['order_num']))$where['a.order_num'] = $param['order_num'];
if (isset($param['order_status']) && !empty($param['order_status']))$where['a.order_status'] = $param['order_status'];
if (isset($param['addr_name']) && !empty($param['addr_name']))$where['a.addr_name|addr_phone'] = ['like','%'.$param['addr_name'].'%'];
if (isset($param['user_name']) && !empty($param['user_name']))$where['b.user_name|b.mobile'] = ['like','%'.$param['user_name'].'%'];
if (isset($param['goods_type']) && !empty($param['goods_type']))$where['a.goods_type'] = $param['goods_type'];
if (isset($param['addtime']) && !empty($param['addtime'])){
list($start,$end) = explode('~',trim($param['addtime']));
$where['a.addtime'] = [['gt',strtotime($start)],['lt',strtotime($end)]];
}
$sql = $this->model->alias('a')->join('member b','a.user_id = b.id')->where($where)->field('a.*,b.user_name,b.mobile')->order('id desc')->select();
$newExcel = new Spreadsheet(); //创建一个新的excel文档
$objSheet = $newExcel->getActiveSheet(); //获取当前操作sheet的对象
$objSheet->setTitle('管理员表'); //设置当前sheet的标题
$newExcel->getActiveSheet()->getColumnDimension('A')->setAutoSize(true);
$newExcel->getActiveSheet()->getColumnDimension('B')->setAutoSize(true);
$newExcel->getActiveSheet()->getColumnDimension('C')->setAutoSize(true);
$newExcel->getActiveSheet()->getColumnDimension('D')->setAutoSize(true);
$newExcel->getActiveSheet()->getColumnDimension('E')->setAutoSize(true);
$newExcel->getActiveSheet()->getColumnDimension('F')->setAutoSize(true);
$newExcel->getActiveSheet()->getColumnDimension('G')->setAutoSize(true);
$newExcel->getActiveSheet()->getColumnDimension('H')->setAutoSize(true);
$objSheet->setCellValue('A1', '订单编号')
->setCellValue('B1', '会员')
->setCellValue('C1', '收件人')
->setCellValue('D1', '手机号')
->setCellValue('E1', '订单总价')
->setCellValue('F1', '下单时间')
->setCellValue('G1', '分类')
->setCellValue('H1', '状态');
/*--------------开始从数据库提取信息插入Excel表中------------------*/
//$i=2; //定义一个i变量，目的是在循环输出数据是控制行数
$count = count($sql); //计算有多少条数据
for ($i = 2; $i <= $count+1; $i++) {
$objSheet->setCellValue('A' . $i, $sql[$i-2]['order_num'])
->setCellValue('B' . $i, $sql[$i-2]['user_name'].'('.$sql[$i-2]['mobile'].')')
->setCellValue('C' . $i, $sql[$i-2]['addr_name'])
->setCellValue('D' . $i, $sql[$i-2]['addr_phone'])
->setCellValue('E' . $i, $sql[$i-2]['total_price'])
->setCellValue('F' . $i, date('Y-m-d H:i:s',$sql[$i-2]['addtime']))
->setCellValue('G' . $i, $sql[$i-2]['goods_type'] == 1?'团品':'引流')
->setCellValue('H' . $i, $sql[$i-2]['order_status']);
}
/*--------------下面是设置其他信息------------------*/
header('Content-Type: application/vnd.ms-excel');
header("Content-Disposition: attachment;filename=".$param['addtime'].'订单'.".xls");
header('Cache-Control: max-age=0');
$objWriter = IOFactory::createWriter($newExcel, 'Xls');
$objWriter->save('php://output');
//通过php保存在本地的时候需要用到
//$objWriter->save($dir.'/demo.xlsx');
//以下为需要用到IE时候设置
// If you're serving to IE 9, then the following may be needed
//header('Cache-Control: max-age=1');
// If you're serving to IE over SSL, then the following may be needed
//header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past
//header('Last-Modified: ' . gmdate('D, d M Y H:i:s') . ' GMT'); // always modified
//header('Cache-Control: cache, must-revalidate'); // HTTP/1.1
//header('Pragma: public'); // HTTP/1.0
exit();
}
二，导入
控制器方法
public function uplaod()
{
//获取表格的大小，限制上传表格的大小5M
$file_size = $_FILES['myfile']['size'];
if ($file_size > 5 * 1024 * 1024) {
$this->error('文件大小不能超过5M');
exit();
}
//限制上传表格类型
$fileExtendName = substr(strrchr($_FILES['myfile']["name"], '.'), 1);
//application/vnd.ms-excel 为xls文件类型
if ($fileExtendName != 'xls') {
$this->error('必须为excel表格，且必须为xls格式！');
exit();
}
if (is_uploaded_file($_FILES['myfile']['tmp_name'])) {
// 有Xls和Xlsx格式两种
$objReader = IOFactory::createReader('Xls');
$filename = $_FILES['myfile']['tmp_name'];
$objPHPExcel = $objReader->load($filename); //$filename可以是上传的表格，或者是指定的表格
$sheet = $objPHPExcel->getSheet(0); //excel中的第一张sheet
$highestRow = $sheet->getHighestRow(); // 取得总行数
// $highestColumn = $sheet->getHighestColumn(); // 取得总列数
//定义$usersExits，循环表格的时候，找出已存在的用户。
$usersExits = [];
//循环读取excel表格，整合成数组。如果是不指定key的二维，就用$data[i][j]表示。
for ($j = 2; $j <= $highestRow; $j++) {
$data[$j - 2] = [
'admin_username' => $objPHPExcel->getActiveSheet()->getCell("A" . $j)->getValue(),
'admin_password' => $objPHPExcel->getActiveSheet()->getCell("B" . $j)->getValue(),
'create_time' => time()
];
//看下用户名是否存在。将存在的用户名保存在数组里。
$userExist = db('admin')->where('admin_username', $data[$j - 2]['admin_username'])->find();
if ($userExist) {
array_push($usersExits, $data[$j - 2]['admin_username']);
}
}
//halt($usersExits);
//如果有已存在的用户名，就不插入数据库了。
if ($usersExits != []) {
//把数组变成字符串，向前端输出。
$c = implode(" / ", $usersExits);
$this->error('Excel中以下用户名已存在:' . $c, "/backend/admin/create", '', 20);
exit();
}
//halt($data);
//插入数据库
$res = db('admin')->insertAll($data);
if ($res) {
$this->success('上传成功！', '/backend/admin', '', 1);
}
}
}
